Classic Sourdough Donuts

Soft, Fluffy, and Perfectly Fried

There’s something extra special about homemade sourdough donuts. They’re soft and fluffy on the inside, lightly crisp on the outside, and full of that subtle sourdough depth that makes them taste bakery-worthy.

If you’re looking for a cozy weekend baking project — or a way to use up sourdough discard in a truly rewarding way — these classic sourdough donuts are a must-try.

Why Sourdough Donuts Are So Good

Sourdough brings a few key things to donuts that regular dough just can’t:

• Tender, fluffy texture

• Light tang from natural fermentation

• Better flavor development

• Soft interior with a golden fried exterior

They’re rich without being heavy, and they stay soft even after cooling.

What Makes These Donuts Soft & Fluffy

A few simple elements make all the difference:

• A well-fed sourdough starter or discard

• Proper resting time for the dough

• Frying at the right temperature (not too hot, not too cool)

• Light handling to keep the dough airy

The result is a donut that puffs beautifully and fries evenly.

When to Make These Sourdough Donuts

These donuts are perfect for:

• Weekend breakfasts or brunch

• Special mornings or holidays

• Sharing with family and friends

• A cozy baking day at home

They’re best enjoyed fresh, dusted in sugar, cinnamon sugar, or finished with a simple glaze.

Ingredients

Dough

• ¾ cup milk, warm (not hot)

• ½ cup active sourdough starter (or discard)

• ¼ cup granulated sugar

• 2 tablespoons melted butter

• 1 large egg

• 2¼ cups all-purpose flour

• ½ teaspoon salt

For Frying

• Neutral oil (vegetable, avocado, or canola)

For Finishing (optional)

• Granulated sugar

• Cinnamon sugar

• Simple glaze (powdered sugar + milk + vanilla)

Instructions

1️⃣ Make the Dough

In a large bowl, whisk together the warm milk, sourdough starter, sugar, melted butter, and egg. Add the flour and salt and mix until a soft dough forms.

Turn the dough onto a lightly floured surface and knead for about 5–7 minutes, until smooth and elastic.

2️⃣ First Rise

Place the dough in a lightly greased bowl, cover, and let rise at room temperature until doubled — about 6–8 hours, depending on the strength of your starter and room temperature.

💡 For deeper flavor, you can refrigerate the dough overnight after the first rise.

3️⃣ Shape the Donuts

Roll the dough to about ½-inch thickness. Cut donut shapes using a donut cutter or two round cutters.

Place the donuts on parchment paper, cover lightly, and let rise again for 30–60 minutes, until puffy.

4️⃣ Fry the Donuts

Heat oil in a heavy pot to 350°F.

Fry donuts in batches, about 1–2 minutes per side, until golden brown. Transfer to a wire rack or paper towels to drain briefly.

5️⃣ Finish & Enjoy

While warm, coat donuts in sugar or cinnamon sugar, or dip into glaze. Enjoy fresh — they’re best the same day.

Secret Tips for Extra-Soft, Bakery-Style Donuts ✨

These little details make a big difference:

✔ Don’t Over-Flour

A slightly soft dough makes fluffier donuts. Add flour only as needed.

✔ Watch the Oil Temperature

Too hot = burnt outside, raw inside Too cool = greasy donuts Stick close to 350°F for perfect frying.

✔ Use Parchment Squares

Cut donuts on parchment and lower them into oil gently — this keeps their shape and avoids deflating.

✔ Glaze While Warm

Glazing warm donuts helps the glaze set smoothly and soak in just enough.

✔ Best Same Day (But…)

If needed, reheat briefly in the oven to refresh softness.

🍩 Bakery Secrets for Extra-Fluffy Donuts

• Use milk instead of water for extra softness

• Don’t skip the egg — it traps air for better rise

• Keep the dough slightly sticky (dry dough = dense donuts)

• Let the dough rise slowly for better structure

• Always do a second rise before frying

• Fry at 350°F for maximum lift

• Optional bakery trick: Replace 1–2 tbsp flour with cornstarch for a pillowy crumb

⭐ Bakery-Level “Extra” Tip

Some bakeries lightly steam the dough during the final rise (cover loosely with a damp towel).This keeps the surface elastic so donuts expand instead of tearing.
